Unusual bug in 4K Nvidia Shield platform cause screen flicker with Vizio M-Series TVs
Stephan Jukic – February 10, 2016
From what we’ve heard, the bug causes the Vizio TV to periodically flicker rapidly if the HDMI cable from the NVIDIA Shield is removed or being connected. To the best of our knowledge at the moment, the issue only seems to affect Vizio M-Series 4K TVs like the M43-C1 and above and applies only to the 4K-specific 60Hz HDMI 2.0 ports. In other words, nobody seems to have reported the problem when they connect their NVIDIA Shield Android TV device to a 1080p HDMI port.
One particular user who contacted Vizio tech support, according to a recent Reddit post in the Android TV forums, claims that the problem is likely caused by the refresh rate of the SHIELD TV going faster than 60Hz and thus causing the TV to behave unusually. However, if this is part of the cause, then it must be specific to Vizio M-Series TVs having an incapacity at handling the higher-than 60Hz refresh of the Shield, since we haven’t heard from owners of other 4K TVs by other brands having the same problem with their HDMI 2.0 ports.
In any case, NVIDIA and Vizio have both been contacted by numerous users and NVIDIA in particular has already established a record of the bug, with a likely fix on the way, assuming the problem originates with their Shield platform. If any of our readers here who happen to have both of the devices in question or a NVIDIA Shield connected to a different 4K TV model from another brand and have experienced similar problems, feel free to leave a comment.
The NVIDIA Shield with Android TV platform offers both access to streaming 4K entertainment and gaming options for users of 4K ultra HD TVs which offer HDMI 2.0 connectivity.
